Abstract

This Ph.D. thesis is about causality in Quantum Mechanics, namely about the possibility to provide a
causal explanation for quantum Einstein – Podolsky – Rosen (EPR) correlations.
The well-known interpretation of the Bell’s Theorem by Bastian Van Fraassen, who inferred that
quantum correlations cannot be embedded in any causal model, compels us to suppose that
microscopic nature cannot have a causal structure and that causality is an anthropological concept.
However, this interpretation is not commonly accepted and this doctoral thesis is the first general
overview of some recent works about causal explanation for EPR correlations. Particularly, it analyses
the possible causal explanations for the EPR/Bohm experiments by means of the Hans Reichenbach’s
model, by means of backward causation models, and by means of models that imply a direct causal link.
In order to do it, it pays particular attention to the Relativistic space-time features and it considers the
studies in the History of Philosophy about the link between causal arrow and temporal arrow.
Moreover, this work aims to endorse the idea that the best way to explain EPR/Bohm correlations
causally is to adopt an indeterministic non-Reichenbachian common cause model, particularly
Cartwright’s general forks model.
My conclusion is that causal models for quantum correlations remain viable, and that there is no
contrast between genuinely indeterministic interpretation of Quantum Theory and causal explanation,
with the philosophical implication that the Causal Realism is still acceptable.
